Recording of and Technical Responses to Coastal Erosion of Touristic Aegean Island Beaches

KICK OFF MEETING

Venue: University of the Aegean, Mytilene, Lesvos, Greece

Mytilene, March 2016

What has been done till now

• Complex Administration Procedure (more or less completed)

• Team in place 1st March 2016

• Equipment tender finished (but incomplete)

• Fieldwork already undertaken in Tsamakia and Eresos beaches (Lesvos)

• Pilot beach in Chios selected (site visit)

W.P. 1.1: Project Management, financial coordination and project web siteW.P. 1.2: Contacts with local authorities/selection of pilot beaches W.P. 1.3: Dissemination

W.P. 2.1: Present/future coastal erosion trends of the selected beaches/islandsW.P. 2.2: Pilot beach experiments (field work)W.P. 2.3: Coastal morphodynamics modelingW.P. 2.4: Riverine supply and coastal hydrological modelling

Discussion?

Fieldwork

Bathymetry Example

Hydrodynamics

Optical system to be installed in Santorini?

Records for 10 minutes per hour, TIMEX & SIGMA generated in situ . Built for 24/7 operation

An example from Gerakas beach, Zakynthos (37°42'27"N, 20°59'10"E )

Calibration

Lens distortion Ground control points (GCPs)

Georectification parameters

Georectified mosaic (for raw snapshots, TIMEX, SIGMA, …)

meters, UTM

Basic products (TIMEX/SIGMA) are georectified and rotated for easier processing and display

Automatic coastline detector

Ground-truthed with manual detections (Velegrakis et al., Nat. Haz. under revision)

Long-term coastline monitoring: Optical system results

Pilot station(s) under consideration
